Missing Mary Road

On August 2, 2007, Russia dropped a titanium capsule bearing its flag onto the Arctic floor, highlighting its bid for a chunk of seabed property thought to contain billions of dollars in untapped energy. The move snagged media headlines as other nations—including the US, Canada, Denmark, and Norway—sped north to make competing claims. Weeks later, hearings began in the US Senate, in which presidents from America’s largest oil, shipping, and telecommunications companies, representatives from the armed forces, and senior Bush administration officials urged the Foreign Relations Committee to ratify the UN Convention on the Law of the Sea (UNCLOS). “In the year ahead we could see a historic dividing up of many millions of square kilometers of offshore territory with management rights to all its living and non-living resources on or under the seabed,” said Paul Kelly, president of the Gulf of Mexico Foundation. “An adviser to developing states preparing their own submissions said recently, ‘This will probably be the last big shift in ownership of territory in the history of the Earth. Many countries don’t realize how serious it is.’”

Never before has the world’s attention been so fixed on the deep ocean. Inflated oil, mineral, and gas prices, coupled with collapsing global fisheries, are pushing industries into remote seas once too expensive to tap. Pressing concerns about global warming are bringing scientists to explore uncharted depths—both to understand how they influence climate and to take the pulse of abyssal life before human impact irrevocably transforms it. At a time when still so little is known about the ocean’s very nature, it has suddenly become a place of extraordinary geopolitical, economic, and scientific value.

This composite image shows the jet from a black hole at the center of a galaxy striking the edge of another galaxy, the first time such an interaction has been found. In the image, it is clearly seen how the jet from the main galaxy on the lower left is striking its companion galaxy to the upper right. The jet impacts the companion galaxy at its edge and is then disrupted and deflected, much like how a stream of water from a hose will splay out after hitting a wall at an angle. The composite image was made by combining data from Chandra, Hubble and several other systems.

wtf?

maybe you don’t wanna open the link in a public environment.

On the origin of the Earth’s moon and how our planet would be different if we didn’t have a moon.

The Moon has been a stabilizing factor for the axis of rotation of the Earth. If you look at Mars, for instance, that planet has wobbled quite dramatically on its axis over time due to the gravitational influence of all the other planets in the solar system. Because of this obliquity change, the ice that is now at the poles on Mars would sometimes drift to the equator. But the Earth’s moon has helped stabilize our planet so that its axis of rotation stays in the same direction. For this reason, we had much less climatic change than if the Earth had been alone. And this has changed the way life evolved on Earth, allowing for the emergence of more complex multi-cellular organisms compared to a planet where drastic climatic change would allow only small, robust organisms to survive.

Humans are evolving faster, apparently.  To the tune of one hundred times faster in the last five thousand years than in any other timeframe in human history you care to name.  Ten thousand years ago, nobody on the planet had blue eyes.  Today, a human being can survive having internalised the dead bodies of her own triplets.
